Biofuels can help developing countries reduce carbon emissions, reduce over dependence on fossil fuels and increase energy security. However, this alternative must be pursued with care to reduce possibility of environmental degradation, deforestation, food shortages and high food prices. One way is to pursue second generation feedstocks. Limiting use of some food crops in biofuel production and mapping out areas for biofuel crop production can also prove helpful.

Home solar kits remain an important strategy in powering rural homes given the challenges of distributing power via grids. With rural areas characterized by low income groups and scarcely dispersed populations, grid power cannot reach everyone. Kenya will be banking on additional home solar kits to connect more homes as announced in the just concluded 6th Annual Global Economic Summit in Nairobi.

A local entreprenuer in Tanzania has devised a solution that seeks to eliminate all the problems associated with unsafe/unclean water and sanitation. It will help locals avoid related diseases. What's more is that his solution is low-cost and requires no power compared to other water treatment technologies. It is also made from local materials, recyclable, and versatile in that it can be tailored to treat water in vartually any location/area. The nano-filter combines nano-filtration technologies with sand-based water filtration techniques. It has already been rolled out in the market and is gaining ground.

The efficiency of waste management is an important aspect of sustainablity - especially with the global amount of waste expected to dramatically increase over the coming decades. Mobile technology from IBM is being used for mapping and tracking waste collection, as well as reporting related data in real-time, in order to enhance related decision-making.

Adoption of biomass power generation technologies in Africa has been challenged by a variety of factors including high capital costs and lack of feedstock. However, with biomass contributing to only 5% of power production in the continent, these projects hold a promise to helping boost the much needed power in developing world. It is not only the largest biomass power plant in Africa, but Gorge Farm AD Plant in Kenya will be Africa's first anaerobic digester.
